ABSTRACT
Tick-borne diseases are of the most important diseases in the world including Iran. This survey was conducted to understand the eco-epidemiology of tick-borne hemoparasitic diseases in Qazvin province, Iran, using Geospatial Information System [GIS]. DNA samples were extracted from livestock blood samples collected from different regions of Qazvin province. 18S rRNA-based PCR targeted Theileria/ Babesia species were done. Initial parameters for mapping the local tick-borne hemoparasitic diseases and raster files were obtained from Iran Meteorological Organization and Iranian Space Agency. Mapping of the parameters in relation to prevalence of these diseases were done. Statistical analysis was used for weighting parameters ranking and predicting spatial distribution in different climatic zones. Vapor pressure, precipitation, and altitude are of several environmental factors correlated with tick abundances. Based on the generated maps and the results of this survey, some predicting results could be used for predicting tick-borne diseases and their control. 9.7% of ruminant blood samples [N=16] were infected with protozoa pathogens from the genera Theileria and all of the specimens were negative regarding to Babesia genera. Results showed that prediction of a very high prevalence of Theileria/ Babesia species and mapping endangered area is possible in different parts of Iran. Based on the environmental conditions, key factors exist for host-seeking and range expansion of ticks
ABSTRACT
Scorpion stings cause a serious problem all over the globe. This study aimed to trace the epidemiological profile of scorpion stings and some common clinical symptoms in Dezful County. Our work is an analytical cross-sectional study of scorpion stings based on medical files of stung patients referred during 2007- 2008. During 2007-2008, 820 cases were registered. 59.9% of the cases were from rural areas. The stings had the most frequency in spring months, particularly in June, when yearly temperature was favorable. Based on the results of this study, scorpion sting envenomation is of clinical importance in this area.
